Prophet Rev2 First Look #2 | Filter - What is it like?


Published on Mar 27, 2019 Synth & Sundry

"The Dave Smith Instruments Prophet Rev 2, a refreshed modern analog polysynth, has a primary low pass Curtis filter which can be switched between 2 and 4 pole slopes.

Let's see how the filter feels. We try the filter with different settings both for cutoff and resonance. The filter affects the sounds coming from the oscillators and removes frequencies which changes the timbre of the sound.

The 2 pole mode has a 12db/octave slope while the 4 pole mode has the steeper 24db/octave mode that has a more pronounced effect (generally suitable for monophonic synth patches).

The main controls are the Cutoff that frequency at which frequencies start to be removed. This starts with the high frequencies and lends the name low-pass to the main filter for the Prophet Rev2. Cut off works hand in hand with resonance which highlights a narrow area of frequencies at the cut off point (where frequencies are being removed). This brings its own sonic characteristics.

It's worth noting that high resonance values lead to self oscillation when in four pole mode. This means that the filter will generate its own pitch.

Recorded through an RME Fireface UC audio interface without any effects or dynamics processing added."

Prophet Rev2 First Look #1 | Oscillators - How do they sound?


Published on Mar 20, 2019 Synth & Sundry

"The Dave Smith Instruments Prophet Rev 2, a 16-voice analog synthesizer, has two oscillators per voice with Sawtooth, Triangle, Pulse and additionally a Saw+Tri amalgam. Additionally each voice gets an oscillator and sub oscillator to round out the sound generation set available to the player.

In this video, we try out some of the sonic possibilities the oscillators on the DSI Prophet Rev2.

Since the oscillators in the Rev2 are digitally controlled analog oscillators, they have very stable tuning. However, part of the pleasing character of an analog synth comes from its imperfection and instability. This brings that back with a vengeance and gives it its own dedicated setting - Osc Slop.

Both oscillators in each voice have a frequency range that extends across 9 octaves and the Osc Frequency controls move through the full spectrum in semi-tone increments. Meanwhile the Fine Tune knob is center-detented and it allows for full a half-semitone of adjustment.

While waveform selection on offer may seem somewhat limited, this is greatly made up by the fact that the Shape Mod knob operates across all wave shapes. The naturally dull triangle shape has a great deal to gain from this feature as it really brightens the sound up a bit (somewhat reminiscent of the 'Metalizer' on Arturia analog synths).
